Rotating type fluid damping joint with elbow-shaped elastomer for vibratory energy consumption

Abstract

The invention discloses a rotating type fluid damping joint with an elbow-shaped elastomer for vibratory energy consumption. The rotating type fluid damping joint comprises a main cylinder body, a rotating core is rotatably arranged in the main cylinder body and connected with a rotary guiding rod and a plurality of pistons, the two sides of the main cylinder body are fixed and sealed by side cover plates, a sealed space is formed in the main cylinder body through a pair of sealing plates and filled with a damping fluid, the pistons are located in the sealed space, the rotary guiding rod is located outside the sealed space and extends out of the main cylinder body, the outer side of the main cylinder body is connected with a fixed guiding rod, the outer end of the rotary guiding rod and the outer end of the fixed guiding rod are connected with a main body structure through corresponding connection flanges, and the rotary guiding rod and the fixed guiding rod relatively rotate around the axis of the main cylinder body, so that the pistons rotate in the damping fluid along with the rotating core to consume energy. The rotating type fluid damping joint has the advantages of being simple in structure, consuming energy by rotation, consuming energy by fluid-solid mixing and the like, and can provide high damping, lower the response of a structure under the action of dynamic disasters and improve structure safety.

Description

technical field [0001] The invention relates to the technical field of vibration-damping structures in civil engineering, in particular to an elbow-shaped elastic body vibration energy-dissipating rotation type fluid damping node. Background technique [0002] Viscous fluid is a kind of fluid material with high energy consumption capacity. Viscous damping devices made of this material have been widely used in aerospace, advanced machinery, civil engineering and other fields. Such devices generally consist of cylinders, pistons, guide rods, sealing bodies and viscous fluids. The piston of the commonly used viscous fluid damper is provided with a throttling hole. When the structure triggers the movement of the guide rod, the piston and the cylinder connected to the guide rods at both ends move relative to each other, and the viscous fluid flows through the throttling hole. A viscous damping force related to velocity is generated to dissipate energy. In recent years, in the f...

Problems solved by technology

However, some existing rotational vibration damping devices of viscous fluid materials based on the principle of fluid energy consumption, such as a rotary viscous fluid damper (ZL201210141974.2), etc., on the one hand, cannot be directly used in the corners of civil engineering structures structurally. control, on the other hand, the conventional principle of fluid pore energy consumption is still adopted
